This invention relates to improvements in door holders, and aims to provide a holder for pivotally mounted doors which may be employed either in combination with or in- 55 dependently of a door closer.

Most door holders now commonly employed are so constructed that they will only hold a door against movement when the latter has been moved to one predetermined position, which is generally substantially ninety degrees to its closed position, and is inoperative at all other positions of the door,'0r at best operative at perhaps one or two-other predetermined positions. It is an object of this invention to provide a door holder by which a door maybe held against pivotal movement inone direction, that is generally against closing, when the door is opened to any desired and unpredetermined angle relative to its closed position; and wherein the holding means may be easily and quickly released to permit the door to be returned to its closed position. I 1 I p Another object of the invention is to provide a door holder wherein, by reversing one portion of the mechanism, it may be employed for a door which swings in the opposite direction.

A further object of the invention is to provide a door holder with a specially constructed resilient arm-by which the shock is cushioned if the door is violentlyswung toits fully open position.

Vith these and other tages in view which will become apparent as the specification proceeds, the invention is hereinafter more fully described with the aid of theaccompanying drawings, in which a preferred construction is shown: In the drawings y Figure 1 illustrates a side view of the invention'connected to a door and door frame, and with the former in open position. Figure 2 is a plan view showing'the invention employed in conjunction with a conventional .cloor closer and connected toadoor and door frame.

i 'ure 11' is an enlarged section of the. flanged disc. 7,

Figure 12 shows one faceof the latter, and Figure 13 is an enlarged sectionshowing the cam mounted in the flanged disc Referring to the drawings, 1 and 2 designate two arms which are pivotally connected to one another at their adjacent extremities in a. manner-hereinafter described. The opposite end of the arm 1 is intended to be mounted'on a door frame 3, and'isusually V pivotally attached to a bracket 4 which is secured to the said frame. The outer extremity of the arm-2 is either pivotally connected to a bracket 5 mounted on a door 3a, as shown in Figure 1, or is suitably arranged on aconventional door closer 6 secured to the said door 3a asshown in Figure 2.:

Integral with one extremity of thearm 1 closed side and open on its opposite side. Projecting substantially centrally through the closed side 7 a of the housingand fixedthereinis an element 8 havinga portion 8a which is multi-sided in cross section extending a short. so distance from the wall 7 a, while its outer'extremity Sbis circular in section. 1

element portion 8?) is a disc-9 which is freely rotatable in the boreof the housing 7, and projecting from its inner side and-integral therewith is an annular flange 9a. Within the flange 9a between the housing wall 7 a and the adjacent side of the disc 9 is a cam IO having a multisided central aperture 10a therethrough which corresponds to the cross section of the element portion 8a and fits thereon so that the cam is held against rotation independently of the arm 1.

Formed in the periphery of the cam 10 and extending the full width of the latter are a plurality of recesses 11 which are preferably spaced equidistant from one another. The bases of the recesses are eccentric relative to the axis of the element 8 on which the cam is mounted, so that the two ends of each recess, which are substantially radially disposed, are of unequal length. In the longer end walls of the'recesses 11 cavities 12 are formed, and each of the latter receives one extremity of a helical spring 14. In each recess between'the base of the latter and the'inner side of the flange 9a a roller'1'5 is arranged with its axis substantially parallel with the axis of the element 8. -The diameter of these rollers is greater than the distance between the shallower'ends of the recesses and the inner side of the flange 9a and less than the distance between the deeper ends of the said recesses and the inner side of the said flange. The helical springs 14 bear against the rollers 15 and tend to force themtowards the shallower ends of their recesses. Thus the flanged disc 9, the cam 10, rollers 15 and springs 14 form a friction clutch by which independent rotation of the cam and disc is permitted in one direction but not in the other.

In the outer face of the disc 9 a plurality of depressions 16 are formed which are concentrically arranged around the central aperture 9?) through which the element portion 8?) passes. 1 i

The second arm 2 at one;extreniity is provided with a plate 18 to form a closure for the open end of the housing 7, and centrally throughthe plate is an aperture 19 to receive the outer extremity of the element 8 which has an axially disposed tapped hole therein to receive a screw 20 by which the said plat-e 18 is rotatably held against the open side of the housing 7; V

Integral with the plate 18 is an outwardly projecting tubular guide 21 in which a locking member 22 is axially slidable, and within the said guide is a spring 23 which tends to move the said member 22 so that its inner extremity projects beyond the inner face of the plate 18. In the outer face of an annular nut 24 by which the spring 23 is retained within the member 22 two transverse grooves 25 and 26 are formed, preferably substantially at right angles to one another. The groove 25 is made deeper thanthe groove 26. Projec ing radially on both sides from the member 22 is apin 27 which is adapted to engage either of the grooves25 or 26. At the-lower extremity of the member 22 a suitable hand hold, such as the ring 22a isp'r'ovided, When the pin 27 rests in the groove 25 the inner ex tremity of the member22' projects "beyond ream rests in the groove 26 the inner extremity of the said member does notproject suficiently far inward to engage any of the said depressions.

The arm 2 consists of a plurality of parts including an end member 30 of which the plate 18 forms an integral part. The end member 30 has a shank3l thereon and from the outer extremity of the latter a project-ion 32 of reduced diameter extends. A second end member 33 is provided which is threaded externally intermediately of its length, terminates at one extremity in a projection 34, similar to the projection 32, and at its other extremity in a lip 35 which is pivotally 'secured to the bracket 5. Between the projections .32 and 34 and having its ends attached thereto is a coilspring 36. 37 denotes a tubular casing extending between the members 30 and 33, which is'axially slidable on the shank 31 and is provided at one extrer'nity with an internal thread to engage the threaded intermediate portion of the member 33. 40 and 41 denote lugs formed on the housing 7 and end member 30 respectively which are adapted to engage one another and thus limit the pivotal movement of the arms 1 and 2 relative to one another.

From the foregoing it will be readily seen that within the housing 7 a clutch member is provided which consists of the cam 10, rotatable' with and within the said housing which is a portion'of the arm 1, and the flanged disc 9 which is adapted to be connected to the arm 2 so as to turn with it, and the springs 14 and rollers 15. The said rollers and springs permit rotation of the flange 9a around the cam 10 in the direction which tends to'move the said rollers towards the deeper ends of their recesses 11, but as soon as the flange is turned the least extent in the opposite direction around the cam the rollers 15 bind between their recess bases and the inner side of the-flange 9a, thereby preventing rotation inthat direction of the flange 9a around the cam 10. While this clutch mechanism only operates when the arms 1 and 2 are turnedrelatively in one direction, and is intended to preventa door from closing, all that is necessary to render the clutch mechanism operative when the arms are turned relatively in the opposite direction is to remove the cam 10, springs '14 and rollers 15 and reinsert them in the flange disc 9 after having turned the cam. over. In this manner the device, without the utilization of right and left hand parts, may'beemployed for doors swinging in either direction.

The construction of the arm 2 is such that ifthe door 3a is violently opened to such an extent that the arm stops 40 and 41 strike one anotherthe' resiliency of the spring 36 permits the tubular casing 37 and member 33 to 5'9 tion about the former,

move outwardly from the member 31 thereby absorbing a part of the shock the door would otherwise be called upon to withstand.
